Caption:
This image depicts a field scientist in the process of capturing fleas found at the entrance to rock squirrel burrows, Spermophilus variegatus, formerly known as Citellus variegatus, which will be analyzed in order to determine their numbers, and whether they were hosting Yersinia pestis bacteria, the pathogens responsible for causing bubonic plague. Often large numbers of fleas can be collected by swabbing the burrow, as was the case here, using a flexible plumber’s snake and a piece of flannel (see PHIL 14293).
